실험 절차

The diphenyl analog of coumarin 6 was prepared by the thermal condensation of 2-aminothiophenol with the diphenyl analog of coumarin 314. 7.5 g of the diphenyl analog of coumarin 314 prepared according to Example 1, 2.45 g of 2-aminothiophenol, 15 g diphenyl, and 15 g phenyl ether were placed in a 50 ml round bottom flask and taken to reflux for 30 minutes. After cooling to room temperature, 50 ml of toluene was added and the product was isolated by filtration, washed with ether, dried in vacuum, and recrystallized from methylene chloride/ethyl acetate.
